2 lessons
4 quiz questions
Lesson 1: Cells and Body Systems
Connect cell structures to body system functions.
Learning goals
- Identify cells as the basic unit of life.
- Explain how cells form tissues and organs.
- Describe how body systems interact.
Cells to systems
Multicellular organisms are organized from cells to tissues, organs, and organ systems. Each level supports functions needed for survival.
Systems interact
The digestive, circulatory, respiratory, nervous, and muscular systems interact to move materials, respond to the environment, and maintain life.
Lesson 2: Information Processing
Trace sensory information from receptors to responses.
Learning goals
- Describe sense receptors.
- Explain how the brain processes information.
- Connect stimuli to responses.
Receptors gather information
Sense receptors detect light, sound, chemicals, pressure, temperature, and other stimuli. Signals travel to the brain for processing.
Responses
After processing information, organisms may respond through movement, behavior, or internal changes.
